Asthma drugs Flashcards
Th2 high asthmatics
respond to normal treatment
Th2 low asthmatics
neutrophilic inflammation
IL17 = glucocorticoid insensitivity
more airway remodeling
albuterol
SABA
levoalbuterol
SABA
terburtaline
SABA
metaproternol
SABA
bitolerol
SABA
salmeterol
LABA
formoterol
LABA
indacaterol
LABA
vilanterol
LABA
beta agonist moa
increase cAMP which leads to smooth muscle relaxation and blockage of mast cell degranulation
beta agonist use
short term bronchospasm release
emergency (SABA, epinephrine)
prophylaxis of exercise induced
first line rescue
SABA
beta agonist ADR
nonselective- tachycardia, hypotension, palpitations
tremors
methyl xanthines
theophylline
aminophylline
methy xanthine moa
unknown inhibit cAMP breakdown by blocking PDE block adenosine receptors inhibit NFkB increase histone deacetylase activity anti-inflammatory
theophylline use
not first line- use if unresponsive to first line
theophylline adr
unpredictable plasma levels liver metabolized narrow TI headache nausea arrythmias seizures
anticholinergics
ipratropium
tiotropium
ipratropium
sama
tiotropium
lama
anticholinergic use
second line- not as good as beta2 agonists
used in combo with beta2
slower onset, last longer
anticholinergic moa
blocks muscarinic receptors to decrease broncoconstriction and mucus secretion
works with increased vagal tone
ipratropium
tiotropium
